The Quattro 415: Built for Large-Scale Precision
The Quattro 415 is Augspurger’s flagship monitoring solution, engineered for high-SPL environments and expansive control rooms where accuracy and headroom are non-negotiable.
- Four 15-inch woofers per side provide massive low-frequency authority and punch.
- A rock maple horn with a high-output compression driver featuring a 99.9% Beryllium diaphragm delivers unmatched speed, clarity, and precision in the mid and high frequencies.
- The system integrates the ET703A super high frequency compression driver powered via the horn’s HF crossover, for effortless “air” and ultra-high extension.
- Paired with the Sub418-ET703 subwoofers, each loaded with dual 18-inch drivers, the system extends deep into the subsonic range while maintaining speed and control.
- Powered by SXE3D DSP amplifiers, the system benefits from networked control, crossover alignment, limiting, and precise EQ tuning for any room.
Together, these components create a system capable of 18,000 watts of total power in its Ultimate Extreme configuration, with 10,000 watts dedicated exclusively to the subwoofers—making it one of the most powerful reference monitors available today.
